The white JBL CBT 50LA-LS Column Loudspeaker with 8 Driversfrom JBL CBT 50LA-LS Column Loudspeaker with 8 Driversutilizes analog delay beam forming and amplitude tapering to accomplish consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers.

The slim, compact design fits well into virtually any architectural decor. The combination of excellent sound quality and pattern control, and compact (20.8" tall x 3.9" wide) design makes the CBT 50LA-LS Line Array Column Loudspeaker suitable for a wide variety of applications, such as retail stores, concourses, transit spaces, fill applications, conference rooms, architectural spaces, audio for video, lecture halls, and other applications where such a combination is desired.

The voicing can be set to match the application through the Music/Speech switch, conveniently located on the side of the cabinet. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances.

The shielded drivers feature dual neodymium magnets for light weight. Copper-capped pole pieces lower the driver inductance and flux modulation. This increases high frequency extension and reduces distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments.

Dynamic SonicGuard overload protection minimizes distortion at high drive levels by limiting low frequency excursion dynamically. This maximizes clarity at high drive levels while protecting the drivers from damage due to overpowering.

A swivel (pan) / tilt wall-mount bracket is included, and ten M6 inserts on the back panel accommodate third-party mounting brackets, or can be utilized to suspend the speaker using M6 forged shoulder steel eye bolts, providing versatility of installation. The loudspeaker can be installed either indoors or outdoors. The drivers are weather treated, and the fiberglass reinforced ABS cabinet with UV resistant paint is suitable for outdoor applications. The external stainless steel screws and the painted aluminum grille resist rusting in harsh conditions.

Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing

Related Questions and Answers

Q: 1. I'm considering using a pair of these for my living room for music & home theater use. Would these work well in this environment? Also, how far does the front baffle of the speaker extend from the wall when using the supplied wall mount?

A: The JBL CBT 100LA-1 are designed for commercial install applications in medium to large sized venues mainly for speech applications, although it is able to be switched for music application to offer a wider frequency response. When mounted with the included wall tilt/swivel mount the face of the speaker will be 13.5 from the wall.

Q: 2. I know that the maximum throw is about 44 ft. But, what is the minimum distance? In other words, how close can I sit before integration is compromised? Is 10-12 ft too close?

A: The JBL Two-Way ScreenArray Cinema Loudspeaker (B&H # JBC211) has a minimum usable distance of about 3'. Ideally, listeners should be within a 20° angle of the front of the speaker.

Q: 3. what kind of amplifier do I use for these speakers?

A: I would recommend the QSC GX3 300 Watt 8 Ohm Power Amplifier, (B&H # QSGX3,) for a two-speaker set-up. If you require several speakers, I would pair them up with a 70- volt amplifier. Please contact one of our representatives for a specific model, based on your requirements.

Q: 4. Can this be mounted sideways or is it only for a vertical setup?

A: The JBL CBT 100LA-1 line array is designed to be mounted vertically, for sound that will reach all the way to the back of a room.

Q: 5. What type of cable or connector does it use?

A: This speakre uses bare-wire tap terminals.

Q: 6. Is this for one or a pair?

A: This is a single speaker.

Q: 7. Maximum throw distance is 15m, but how close can the front be before driver integration and directionality compromises performance? Is 10 - 12 ft too close?

A: For all of the C211, The Horn is aimed down 10° and the system sums at about 3’ feet between the Woofer and Horn. The C221, C222, C222HP use a dual dissimilar technology that beams the HF downwards as required for commercial cinemas with stadium seating. I would not recommended these for home installs(with Limited Height) if the seats are not within the -20° angle of the horn.

Q: 8. Is anyone using this with a full rock band (guitar, bass, drums, keys, multiple vocals) as your FOH PA system? If so, thoughts?

A: This unit could be used as a FOH speaker for a rock band. A mixer would be needed to accommodate the multiple inputs required for a full band, and that would feed into the speaker. The speaker could handled small to medium sized venues.

Q: 9. Is it okay to Bi-Amp JBL C211?

A: The JBL Two-Way ScreenArray Cinema Loudspeaker BH #JBC211 may be bi-amped: For Single-wire passive operation, leave the jumpers in place (jumpers link the LF+ and HF+ terminals together and the LF- and HF- terminals together). For Bi-wire passive operation, remove the jumpers and wire the LF± and HF± terminals to the respective amplifiers Designed for small cinemas and VIP rooms for a maximum throw of 52'

Q: 10. Can I use this on a 70v amp like the JBL CSA 1300z?

A: The JBL CSA 1300Z Single-Channel 300W Amplifier can operate at 8 ohms, so you can use it to power one JBL CBT 70J-1 Line Array Column Loudspeaker.
